Group photoWho would you vote off the island?
This three-year tv-series would go on to be one of the all-time most popular in reruns; it has never been off the air somewhere in the world. The pilot episode was never broadcast on the network as is due to cast changes but, like Star Trek, used in a later episode as a series of flashbacks. It was only in the pilot that we heard the Skipper's first name (Jonas Grumby) and Gilligan's first name. The Professer's name, by the way, was given as Ray Hinkley in at least one episode.
In case you're the one person left in the world who hasn't seen an episode of this series, here's a description:
The SS Minnow leaves Hawaii for a three-hour tour & gets caught in a storm. Well-meaning but inept Gilligan (the only crewman) throws out the anchor, with no rope attached. The next day, Skipper & Gilligan (Alan Hale, Jr & Bob Denver) wake up on an uncharted island with the passengers:

For an uncharted island, they were always being visited by guest stars. One week it might a rock band looking for solitude from their screaming fans, a biplane pilot Wrong Way Feldman (Hans Conreid), an astronaut in a space capsule, or a bored big game hunter who decides to hunt down Gilligan in a spoof of "Most Dangerous Game" starring Rory Calhoun (which was also later spoofed by Ice-T in his movie Surviving The Game)
The island lagoon was built right in the studio parking lot so when the series ended, it was simply a matter of removing the water and hauling away the sand to turn Gilligan's lagoon back into a paved parking lot.
Russell Johnson has starred in at least one Mystery Science Theater 3000 movie and in recent years has done voice work including the syndicated radio series Imagination Theater, which is heard here in California on San Diego radio station KFMB 760 every Sunday and streaming on their website at 10pm/1am EST followed by a Twilight Zone radio episode. He had previously been one of 3 stars in Western TV-series "Black Saddle" (January 1959 to September 1960) as a Marshall following an ex-gunfighter trying to go strait.
Alan Hale, Jr., had been in a number of movies, usually as secondary characters, and starred in the 11/52 to 3/53 TV-series "Biff Baker, USA" as an international importer who travelled all over the world with his wife & kept running into spies. It was not a comedy
Jim Backus had a long career in radio and TV sitcoms like "I Married Joan" and "The Jack Benny Program," and movies starting in 1949 up to Kurt Russell's 1972 invisible man movie "Now You See Him Now You Don't." His 1950s Mr. Magoo cartoons as the voice of Magoo became the primetime 1964/65 series after the popular "Mr. Magoo's Christmas Carol" broadcast. He also wrote 3 books as well as numerous radio & TV scripts. When Hollywood decided to do a live-action Mr. Magoo movie, Backus was in ill health (from which he never recovered) and Leslie Nelson was cast in the role.
Natalie Schafer had a long comedy movie career starting in 1944, and was an actress on stage before that. Other than guest roles, this was her only TV-series.
After Gilligan's Island, Bob Denver costarred in "The Good Guys" 1968-70' about a beachfront diner, costarring Herb Edelman & Joyce Van Patten. It was renewed after its first year but then cancelled mid-season in January 1970. Denver had previously been in the 4-year TV-series "The Many Lives Of Dobie Gillis" 1959-63, as a bearded beatnik friend of Dwayne Hickman. The series followed Bobie thru high school, the Army (1961) and finally college. The series had a large supporting cast over the years including Tuesday Weld and Warren Beatty in 1959/60, Sheila James as Zelda and William Schallert as Mr. Pomfritt. I also think a certain bearded beatnik in Scooby Doo was inspired by Bob Denver's character Maynard.
Gilligan's Island ran on CBS all 3 years, though at a different time & day each year.
1964/65 @ 8:30pm Saturdays following the Jackie Gleason Show. Oddly, rival NBC scheduled the primetime animated series "Famous Adventures Of Mr. Magoo" at 8pm, which would have encouraged Jim Backus fans (the voice of Magoo) to change the channel to CBS at 8:30
1965/66 @ 8pm Thursdays following The Munsters
1966/67 @ 7:30pm Mondays competing with The Monkees over on NBC at the same time. The Monkees outlasted Gilligan's Island, followed by I Dream Of Jeannie in 1966/67 and The Man From UNCLE n 1967/68. Gilligan's Island was followed years later by a series of Gilligan's Island movies.

Take the Gilligan's Island Poll: which one would you vote off the island first? The last time I checked, Mrs. Howell and Regis had a third of the vote each, with no one else even close. He never shoulda irritated everyone by firing Kathy Lee.
